$sockbr

$sockbr is set to the number of bytes read by a /sockread command. It is used to test whether any information was in fact read from the buffer.

Example

on 1:sockread:testing:{
 if ($sockerr > 0) return
 :nextread
 sockread %temp
 if ($sockbr == 0) return
 if (%temp == $null) %temp = -
 echo 4 %temp
 goto nextread
}
